Radiolarians which settle through the oceanic water column were
recovered from three stations (western Tropical Atlantic-Station E,
central Tropical Pacific-Pi and Panama Basin-PB) using PARLUX
sediment traps in moored ...

The objective of this Thesis was to interpret the structural development of slowspreading
ridge segments by: 1) delineating the nature, magnitude, and relative importance
of primary tectonic and volcanic processes that ...

Volcanic accretion at the fast-spreading East Pacific Rise (EPR) occurs over a ~2-4 km
wide neo-volcanic zone on either side of the axial summit trough (AST). Eruption ages
are critical for understanding the distribution ...

This thesis studies interactions between mid-ocean ridges and mantle plumes using
geophysics, geochemistry, and geodynamical modeling. Chapter 1 investigates the effects
of the Marion and Bouvet hotspots on the ultra-slow ...

Half of the ocean crust is formed at spreading centers with total opening rates less
than 40 km/Myr. The objective of this Thesis is to investigate temporal variations in
active ridge processes and crustal aging at ...

Filtered and Earth-referenced ADCP data from the B92, B97 and S97 IOEBs were demodulated to remove inertial and near-inertial
tidal frequencies, in order to highlight the low frequency components for examination of Arctic ...

Pelagic sedimentation is the primary modifier of topography generated by ridge-associated
volcanic and tectonic processes. This thesis represents an effort to understand the
processes of, and the general distribution of, ...

The modern depositional environment of the northern
epicontinental Barents Sea varies from proximal to distal
glaciomarine. The regional surface sediment distribution is
controlled by erosion of shallow banks of the ...
